To all 'whom it may` concern:

Be it known that I, JOHN WEIL, a citizen of the United States of America, residing at Manseld, in thecounty of Richland and State of Chio, have invented certain new and useful Improvements in Swings, of which the following is a specification.

This invention relates to a swinging parallel bar mechanism for swings in combination with a stand, canopy top, and swing frame.

One of the objects-of this invention is to provide a swinging mechanism comprising pivotally and removably mounted, spaced apart, parallel supporting bars, which are hung from thc upper portion of the ends ot a stand constructed to provide spaced apart, open ends, the free ends of the parallel bars bein pivotally secured to the base bars of the rame of the swing, thereby movably supporting and suspending the swing frame for horizontal movement.

A further object is to provide a swing that will permit the supporting member thereof to be constantly maintained upon a horizontal plane during its swingin movement and while at rest thereby obviating the tilting of the supporting member when it is manipulated to force it to oscillate for the purpose intended.

Another object consists in providing a swinging mechanism that can be disassembled or assembled for operation in combination with a swing stand and swing frame without the use of tools or the removal of bolts or other fastening means, and further providing means of constructingI the swing stand, swinging mechanism and swing frame so that they can be used conjointly; said elements also being arranged and adapted to be folded in a compact form to economize in space for shipping purposes and for ease and convenienceA in transporting same.

Another object is to provide a swing frame with legs having base connectin bars provided thereon to which the paralle bars Aota,swinginmechanism are pivotally attached instea of being attached directly to the supporting member of the swing frame (asis practised in the construction of the swing mechanism) thereby permitting, Ie;,\1 1,se: or' longer parallel supporting bars without. increasing the height of the swinglor itsfallied parts, the resultant being that the radiusof the arc traveled by the' supporting bars is greatly increased.

A further object of this invention is to suspend the swing frame for oscillation by pivotally attaching the free ends of spaced parallel supporting bars to the base bars of the swing frame thereby providing for increased travel o swing frame and parallel supporting bars without increasing the rade of travel of said mechanism as would ollow if it were desired to increase the travel of an ordinary swing frame which is ordinarily supported from one pivot for oscillation.

A further object of this invention is to provide a double acting power crank mechanism which is operated by a. treadle or the like for imparting movement to the swinging mechanism.

Another feature of this invention is in obtaining a greater distance of travelof the swinging mechanism which is accomplished by constructing the sides of the seat with legs, and providing base bars therefor which lie near the floor level, permittin the use of long bars by means of which t e radius of the arc traveled by the swin mechanism is greatly increased, due to t e increased distance from the fixed points of suspension on the swing stand, `to the movable points of suspension on the base bars of the swing frame.

I attain these and other objects by the mechanism illustrated in the accompanying drawing in which:

Figure 1 is a perspective view of the swing stand, swinging mechanism, swing frame, and operating mechanism therefor, showing the parts assembled and ready for USB.

showing one end of the .swing frame, operating mechanism, the stand and canopy top frame being shown in position for normal use in full lines and in its adjustable position in dotted lines, las used for outdoor sleeping.

Fig. shows detail side and end views of the means of pivotally and removably mounting the parallel bars to the swing frame and stand.

In the drawings reference numerals 1 and 2 indicate frames which constitute the ends of astand. The frames are hinged to the lfloor bars 3 and 4 and rigidly locked in a vertical position when used for supporting the swinging mechanism and swing frame.

A part of the swinging parallel bar mechanism comprises two bars 5 and 6 of pre determined length which are pivotally hung from the upper portions of the frames 1 and 2 and arranged thereon to aline with each other. Bell cranks 7 and 8 are pivotally hung from the upper portion of the frames 1 and 2. p

Bars 9 and 10 of shorter length than the bars 5 and 6 are pivotally attached to the bell cranks and 'suspended therefrom. The link bars and connected bell cranks provide one part of the swinging mechanism and the bars 5 and 6 the other; part. The respective links, bell cranks'and bars are pivotally suspended from the upper portion of -the frames, spaced apart a predetermined distance from each other and held on a plane, in alinement with, and in parallel relation to each other thereby forming a swingingl 'parallel bar mechanism to suspend the movlng frame.

A swing frame is constructed of sides 11 and 12 having legs 13 and 14 preferably formed integral with base connecting and supporting bars 15 and 16. The free ends of the short bars 9l and 10 and bars 5 and 6 are pivotally attached to the base bars. L shaped brackets 17 are'secured to the sides 11 and 12 of the swing frameleaving the top portion thereof spaced apart from the sides.

A sup ortingframe member 18 preferably ma e of angle iron is supported upon the brackets, one part ofthe angle iron fitting` in the space between the sides of the swlng frame and the top portion of the L shaped brackets. The gravity of the suporting member and the juxta osition reation of its ends to the sides o theswing frame rigidly maintain the sides of the swing frame in a vertical position.

Braces 19 are pivotally and singularly ares of the swing frame on one end and their opposite ends are pivotally connected to the supporting member, thereby movabl connecting the sides and supporting mem er to permit the folding of the elements comprising the swing frame for convenience in shipping and transporting.

The supporting member can be arranged and designed for a bed, cot, couch, seat, chair or the like as desired. A back 20 is hinged lto the supporting member and is held in a predetermined inclined position by a bar 21. The bar is preferably provided with hooked ends to engage the aper- .tures 22 in the sides of the swing frame and the back 20 (see Figs. 1 and 2).

A folding and adjustable canopy top frame 23 is mounted upon vertical standards 24. The canopy top frame is held and can be adjusted and maintained at any height desired with respect to the stand by the manipulation of the strap clamps (see Figs. 5 and 6).

The preferable manner of hangingthe parallel bars for rapid and convenient assembling and disassembling of the swin(lr frame Without tools, the removal or use orf bolts, or the like, consists in securing rivets '26 or the like to the stand having enlarged concentric heads 27, the enlarged heads passing through apertures 28 thereby permittingl the body of the rivet to engage the slots 29 and pivotally support the parallel bars upon the end Walls of the slots.

The operating mechanism of the swinging mechanism is constructed and connected thereto as follows; A treadle 30 is pivotally connected to the base bars 15 and 16 extending outwardly in front of the sup.

treadle in close proximityto the supporting frame member.

When it is desired to disassemble the complete sWing mechanism for shipping or transporting purposes, the parallel bars and operating mechanism including the treadle are removed and the sides of the swing frame are folded from the position shown in Fig. 2 underneath the supporting member and the back is folded upon the top of the supporting frame member (see Fig. 3).

The end fra-mes of the stand are folded toward each other and lie adjacent to the floor bars. The complete swing mechanism being then folded in compact'form, it can be easily and conveniently shipped or transported. l

4 the swinging mechanism is shown attached to a ceiling or the like in which case it is obvious that the stand is not used. In Fig.' 6 the Vdotted line position of the canop top frame is shown as being the preferab e adjusted osition when the swing is used out of doors, or sleeping purposes.

The operation of the swinging mechanism Attention is called to the fact that in Fig.-

uml

whichearries the swing frame is as follows:

Pressure is exerted upon the treadle in al downward direction and this has the eiect of exerting a pull through the medium of V the link levers upon the bell cranks and simultaneously therewith the treadle pushes the base bars which are attached to thelegs of the sides of the swing frame and the parallel bars rearward, thereby applying the power of a double crank mechanism to impart movement to the swing mechanism when Essure is exerted upon/the treadle as descri V Attention is called to the fact that by a slight pressure upon the treadle, movement is imparted to the swing because of the` fact that the swing is `suspended upon a parallel bar swing mechanism which greatly elongates the Swingin arc traveled b the parallel bars; hence t e grade ascen ed by the y swinging mechanism carrying the load is great y reduced and the driving power necessary to drive same also decreased.

What is claimed is: f' 1. In a swing, a stand, a parallel bar swinging mechanism, pivotally supported by the stand and movable for imparting moveconnectors.
